HYOYLN has been staying busy in Los Angeles, most recently posting a special version of D-Hack's 'OHAYO MY NIGHT' to her official YouTube channel. 

In the video, HYOLYN and D-Hack are seen comfortably singing together inside of a record store with vintage LPs and televisions surrounding them.  

Also included in the video is heartwarming footage of HYOLYN singing at her friend's wedding.  She revealed, "OHAYO MY NIGHT, where I gathered all the emotions I felt after listening to this song and interpreted it in a different way from my perspective. While making and singing, I was very happy, comforted, and reassured. Above all, Thanks to D-Hack, who joined me in this video, and my friend who recently got married. This live clip became a very precious video for me."
